SPECIFICATION forming part of Letters Patent No. 250,831, dated December 13, 1881,

' Application filed September 8,1881. (No model.)

I 0 all whom it may concern:

Be it known that I, MONTGOMERY CUNNING- HAM MEIGs, of Romney, in the county of Tippecanoe and State of Indiana, have invented a new and useful Improvementiu Cultivators, of which the following is a full, clear, and eX- act specification.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of my improvement, part being broken away. Fig. 2 is a sectional side elevation of the same, taken through the line a: w m, Fig. 1. Fig. 3 is a front elevation of the same. Fig. 4 is an elevation of the drawbar cross-head, the draw-bar being shown in section.

The object of this invention is to facilitate the controlling of cultivators.

The invention consists in the combination, with the plow-beams, hinged to each other at their forward ends, and the draw-bar, of theangular bars, the cross-head having frictionwheels, and the friction-wheel pivoted to the slotted hinge-pintle, whereby the resistance of the ground and the draft-strain are made to keep the said beams in place; and also in the combination, with the hinged plow-beams, of the inclined guide-blocks, whereby the stalks of the corn being cultivated are made to regulate the width of the cultivator, as will be hereinafter fully described.

I will describe my improvement as applied to one-horse oultivators, but do not limit myself to that use, as it can be applied with advantage to one-horse grain-drills and two-horse cultivators and harrows.

A are the side bars or beams of the cultivator, which are connected at their forward ends by ahinge,B, so that their rear ends can move freely toward and from each other.

To the beams A are attached cultivator or barrow teeth 0.

To the upper sides of the forward ends of the beams A are attached the forward ends of the handles D,the rear ends of which are held in proper position by brace-bars E attached to them and to the rear parts of the beams A.

To the beams A are attached the ends of angular bars F, with their angles projecting inward and toward each other.

.quired.

G is a cross head or bar, the ends of which are bent forward, are slotted to receive the rear arms of the angular bars F, and have small wheels H pivoted to them at the inner ends of their slots, to rest against the rear edges of the inclined rear arms of the angular bars F. The cross-head G is attached at its center to the rear end of the draw-bar I, which passes through a slot in the projecting upper end of the pintle J of the hinge B, and to its forward end is attached the whiffletree K.

To the hinge pin or pintle J, at the upper end of its slot, is pivoted a small wheel,L, for the draw-bar I to rest against to diminish the friction as the said draw-bar moves forward and back.

With this construction the resistance of the ground against the teeth 0 tends to force the beams A'into positions parallel with each other, and the draft-pressure of the cross-head Gr against the inclined rear arms of the angular bars F tends to force the rear ends of the beams A outward. These two forces exactly balance each other, and thus keep the beams A in proper position, and at the same time allow the rear ends of the said beams to be easily moved in and out by the plowman bymeans of the handles D, to follow crooked rows and avoid irregular hills. Several holes are formed in the forward arms of the bars F to receive the fastening-bolts, so that the inclination of the rear arms can be regulated, as may be re- To the outer sides of the rear ends of the beams A are attached tapering or wedge shaped bars or blocks M, which strike against the cornst-alks when cultivating large corn, so that the rear ends of the said beams will be 0 pushed inward by the said stalks to keep the cultivator at the proper width to cultivate the whole space between the rows.

Having thus fully described my invention,

I claim as new and desire to secure by Let- 5 ters Patent- 1. In a cultivator, the combination, with the hinged beams A, of the cross-head draw-bar I G and the angular bars F, substantially as herein shown and described, whereby the reioo sistance of the ground and the draft-strain are made to keep the said beams in place, as set forth.

2. In a cultivator, the combinatiomwith the angular bars F and the cross-head draw-bar I G, of the rollers H, substantially as herein shown and described, whereby the said crosshead is made to move easily upon the said an- '5 gular bars, as set forth.

3. In a cultivator, the combination of the beams A, angular bars l and the cross-head draw-bar, constructed substantially as herein shown and described, with the ends of the 1 o cross-head G bent forward and slotted, whereby the said cross-head is kept in place upon the angular bars, as set forth.

4. The combination, with the beams A, of the angle-bars F F, the cross-head G, the draw-bar I, and the slotted hinge-pintle J, as [5 shown and described.
